Affiliate Marketing Secrets

I’m a new MMR and PLR eBooks seller and I’m sending them through email forwards to my customers right now, I’m looking for a website that sells good quality ebooks in bulk, maybe a membership or something, and I would relly rather that they provide a link unique to each of these ebooks, so when I sell them I can just send the link to my customers and they can download it directly without having to go to a website and get spammed.
Affiliates welcome 🙂
